Oracle SQL & PL/SQL Fundamentals
Oracle SQL and PL/SQL Fundamentals training delivers the fundamentals of SQL and PL/SQL along with the
benefits of the programming languages using Oracle Database technology. It helps you understand the
benefits of powerful programming language, while teaching you real-world scenarios. In this course, you will
gain the practical knowledge to write PL/SQL programs. You will learn to build stored procedures, design and
execute modular applications, and increase the efficiency of data movement.
Course Description
The Oracle PL/SQL language is a flexible procedural extension to SQL and increases productivity, performance,
scalability, portability and security. This course introduces the delegate to Oracle's PL/SQL programming
language and provides practical experience in writing stand-alone programs, developing database triggers and
implementing stored functions, procedures and packages. It also introduces some of Oracle-supplied
packages.
